摘要
基于牛顿冷却定律的冷却法测量金属比热容实验是大学物理基础实验中一个重要的传统热学实验项目,而温度传感器测试及半导体致冷控温实验这一较新引入基础课教学的热学实验项目,主要训练学生理解并掌握温度传感器的测温原理及准确标定传感器的温度电压关系。文中对两个实验项目的操作方案的合理性和数据处理过程进行了分析对比及探讨,分析讨论了实验室环境下不同测温范围对两个实验结果误差的影响。对比法讲解两个热学实验项目,对学生实验教学效果的改善作用明显,提高工科专业学生分析解决实际应用问题的兴趣及实践探究动手能力。
Based on Newton’s law of cooling,the measuring metal heat specific experiment is an important part of the college physics experiment and traditional thermal experiment project.The temperature sensor testing and semiconductor refrigerating temperature control experiment that it is a newly introduced basic course teaching of thermal experiment project,which mainly trains students understanding and mastering the temperature measuring principle of temperature sensor and precise temperature calibration of the sensor voltage.The rationality of the solution to the operation of the two experimental projects and comparison of data processing are analyzed and discussed,analyzed and discussed the different test in laboratory environment.With the comparative teaching method applied to explain the two thermal experiment project,it is obvious effect for students to improving experiment teaching effect and enhancing engineering students analysis to solving the problem of practical application.
